I adjusted my rear belt tension the other day. What's happening is that when I torque down the right cone nut (axle nut), that cam adjuster on the right rotates leaving about a 1 mm space between the cam and the tab on the swingarm. The cams on both sides are suppose to sit flush on those little tabs on the swingarm. But, for the life of me, I can never get the right one to keep in contact with the tab. I've even pulled out the axle a little bit and took off and examined the cam to see if there is a manufacturing imperfection, but none is present. I use a wrench on the left side to keep the cam adjuster/belt tension in place while I tighten down the right side axle nut. The wheel still appears lined up correctly it's just that the cam (or big washer) won't stay in contact. When the cam does rotate on the right, it appears only the cam is moving and it doesn't appear the axle moves so I think the wheel is still linied up on both sides. Any suggestions?
